3/8-16 X 1-1/8" 六角頭螺絲 | 5級鋼黃鋅 | 全牙 (100/包)

These threads came out of the bag looking clean and uniform, no bent ones or stripped plating that I could spot. The yellow zinc finish has a nice even color and they seated perfectly with a standard socket, so the rest of the box is just sitting in my drawer waiting for the next project.

I needed a handful for a quick repair on a piece of shop equipment, and the fully threaded design made it easy to get just the right bite without any extra space. The hex head fit my socket perfectly without any wobble, too.

The yellow zinc coating on these is even and bright, and the threads are clean enough that they start by hand without any binding. I've used about forty of them so far for a machine guard and every single one seated flush.
